IWC Big Pilot Markus Bühler Tourbillon 43mm

How it wears

Wears larger than its 43 mm case suggests

IWC Big Pilot Markus Bühler Tourbillon 43mm measures 52 mm lug-to-lug on a 43 mm case, a lug-to-lug ratio of 1.21 against a database median of 1.18. That span is longer than 94% of the 8,093 watches in this database and longer than 84% of the 43 IWC watches listed.

A flat wrist width of 58 mm (2.28 in) or more keeps it in the balanced range, and from 70 mm (2.76 in) it starts to look compact. Below 52 mm (2.05 in) the lugs are likely to overhang the wrist. Flat wrist width is measured straight across the top of the wrist, not around it.

At 14.6 mm thick it is on the thicker side, thicker than 90% of the watches with a listed thickness.
